Be it knownthat I, TimononnPnmiufa citizen of the United States,"residing at Veyerhauser, in the county of Rusk and State of \Visconsimhave inventedgcertain, new and useful Improvements nBrakeA Actuating Mechanism; and I do hereby declare the following to be a full, clear, and

exactdescription of the invention, such as will enable others skilledin theart'to which it appertains to make and use'the same.

My invention has for its object to 'provldet -an extremely siniple and highly eificient-car',

brake actuating mechanism, end, tqlthisend, it consists of the novel devices, and combi nations of devices herein fter descr bed and defined in the claims. 3 In the accompanying drawings, which L" illustrate the invention, like characters. indi cate like parts throughout theseyeral views,

Referringto the drawings,.F1gure 1 is a plan iew of a car truck, some parts being- ;removed, and havingapplied thereto, in

Of the parts otthe freight cartruckillustrated for thepurpose of gshowing the invention applied in working position, it is only necessary to note the Wheels 1, axles 2,

journal boxes, 3, truckside frames 4, bglsten columns 5, sand plank v6, and ,shoeequlpped;

brake heads 7, suspendedfln the customary t manner'from brakehangers 8 vThe truck bolster and supportin springs are removed in order to more clear y show the-invent on applied to the'truck. All of the parts thus; far described may be of the standard or any desired construction. 1 r,

. To keep the brake shoes properl post. tioned' on the treadflanges of the 'w eels 1, and against lateral movements, the brake shoes T-are each provided with a pair of oppositely projecting ears or lugs 29, in which are mounted horizontally rejecting guide pins '30, arranged to 'e'rn race the wheels. All of the pivot pins 12', '14 22 and 28,"are held against removal from the seats split ke s31. "By the use of the above described hrake actuating-mechanism, the customary brake beam, safety hangersfor the brake beam, dead lever, dead ever "guides, .and' bottom rod are entirely dispensed I with, thereby is, of course, evident that the elements of the improved brake mechanism-"may be set in various different positions to 'fit car trucks of different designs. Obviously, the

the brake actuating mechanism are such that the pressure on the brake shoes "will ,be edkually" distributed onto the several car 4W eels. By pivotally mountingth'e guides '18, the same will turn to permit free move-' ments of the primary toggle and arm extensions '16 during the setting and' releasing of the brakes. The length and position of the brake lever 23 issu'ch as -to'fpermit the of the 'follovvi'n truck.

It is also understood that the improved brake actuating mechanism may be attached to brake-shoe equipped heads of the standard or of any desired construction -and,'"of

course, the customary brak'e hangers may be 1 v v I w (1 employed.
